Each of our standard Laboratory Viscometers/ Rheometers are supplied with an internal spring used to calculate the viscosity of a material. These springs have different measuring capabilities:

LV is for low viscosity materials and can measure the thinnest materials. Typical examples include inks, oils, and solvents.

RV is for medium viscosity materials than those measured with an LV torque. Typical examples include creams, food, and paints.

HA is for higher viscosity materials than those measured with an RV torque. Typical examples include gels, chocolate and epoxies.

HB is for even higher viscosity materials than those measured with an HA torque spring. Typical examples include asphalt, caulking compounds, and molasses.

The BF35 maintains a constant shear rate and is an accurate and versatile tool for drilling fluid measurements.

The BF35 operates on a different measurement technique than traditional standard Brookfield Viscometers. The sample is placed in the cup and the spindle/chamber combination is then immersed into the sample. When the motor is turned on, the chamber rotates while the spindle remains stationary. When the dial reading becomes stable, the torque reading is recorded and manually converted into a viscosity value in centipoise.

FEATURES AND BENEFITS :

1. Easy speed changes.
2. Conventional oilfield rotor, bob and torsion spring.
3. Adjustable table height to accommodate a variety of beaker/container sizes.
4. Shear stress values displayed on easy-to-read lighted dial.
5. Maintains a constant shear rate under varying input power and drilling fluids.
6. Measures viscosity of drilling muds and fracturing fluids according to established methods from the American Petroleum Institute and the ASTM.

SPECIFICATIONS :

The original Brookfield Dial Reading Viscometer has been the lab standard used around the world since 1934. Current units have been been improved with a multi-speed electronic drive and ergonomically designed speed control knob so selection of any one of the 10 pre-set speeds (8 speeds on LVT models) is quick and easy. The direct-drive design results in extremely quiet operation and greater versatility while the universal power supply facilitates the use of worldwide power sources.
